The Piedra BESS project is a proposed 100.4 MW battery storage project located in Freestone County, Texas. Developed by Piedra Solar, LLC, the project is interconnected within the Electric Reliability Council of Texas (ERCOT) region. It entered the ERCOT interconnection queue as queue ID ERCOT-25INR0169 on September 2, 2022, with a proposed commercial operation date of December 31, 2026.
The project's Interconnection Agreement (IA) has been executed as of July 2, 2024. The point of interconnection is the Tap 345-kV line Navarro (68091) _x0013_ Limestone (46020). The project is currently listed as active in the interconnection queue.
